I Letters Patent N 106,587, dated August 23, 1870.

IMPROVEMENT IN ATOMIZING--TUBES 'lhe Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that I, THOMAS J. HOLMES, of Malden, in the county ot' Middlesex and State et' Massachusetts, have invented certain improvements in Atomizing-Tnbes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing making part of this specification, in which- Figure l is a perspective View of an atomizngtube of my improved construction.

Figure 2 is a longitudinal vertical section through the center of the same. l

Figure 3 is a longitudinal vertical section through the center of an atomiziug-tube of different construction.

Atomizing-tubes as heretofore constructed for disspating into spray and distributing medicinal liquids for inhalation in throat and other diseases, and for diffusing liquid perfumes through the air to render it odorous, are frequently liable to be obstructed by sediment at or near the liquid point, or discharge oriiice, and an inconvenience arises from the trouble and delay incurred in removing the obstruction.

To obviate the above-mentioned ditiiculty is the object of my invention, which consists in providing one of the tubes with a joint at or near the liquidpoint, in order that it may be readily removed to obtain access to any obstruction at this point; and my invention also consists in so constructing and connecting the air and liquid tubes, that the air will be forced through the air-tube in a line passing centrally through the orifice of discharge or liquid point, whereby the atomizer is rendered lighter and more compact than thoseJ as heretofore constructed.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the Y manner in which I have carried it ont.

In the said drawing- A is a rubber tube, provided with au air-chamber, B, one end of the tube being provided with a bulb, G, while the lother end is fittedl or sprung over a projection, a, screwed on the outer end ot' a short horizontal tube, D, the inner end of which is provided i E at its junction therewith.

The horizontal tube D is contracted at its inner end, so as to form a very small orifice, c, through which air is forced by pressing the bulb C by hand, the point of the air-tube at the orifice c extending t0 or slightly into an orifice, (l, in the center of the short portion b, through which the contents of the vertical or liquid tube E are driven by forcing a cnrrent of air through the air-tube over its top, so as to create a vacuum at this point, the center or axishof the air-tube and that of the short portion l, and oritice of discharge or liquid point -forming one and the same straight line, by which construction the atomizer is rendered lighter and more compact.

lhe position ofthe air and liquid tubes may be reversed, and each tube be employed for performing the ofiice of the other, in which case thc projection a must be screwed onto the bottom ofthe liquidtube, which is provided with a screw-thread for this purpose, in order that the rubber tube A may be connected therewith.

There the liquid-tubel is employed as an air-tube the spray ejected at the 4discharge orifice is finer than the spray produced when the parts are in the position` shown in figs. l and 2.

In tig.4 3 the construction -of my atomizing-tube is moditled to render it applicable to throat diseases, representing the lower or vertical branch of a liquid tube, acrosss thc top of which,aud connected therewith, extends a` horizontal branch tube, c, both ot' which formthe liquid-tube G.

Through the center of the horizontal branch e passes a small air-tube, H, provided, at its outer end, with a projection, f, over which v to fit the end of the rubber tube A. e

lhe inner end of the air-tube is contracted to form a small orifice, 5, and projects slightly into the orilicc of discharge or liquid point 6 inv .t cap, 7, on the, cud of the horizontal branch-tube c, thc cap being made removable, and scewing over a thread on an eul-.n'gcd portion ot' the air-tube,just in the rear of the oritice 5, the port-ion of -the air-tube of small diameter. cx, tending a short distance lbeyond the place where thc removable cap 7 screws onto the horizontal branch c,

and channels S being ciit across the screw-thread on the enlarged portion of the inner end ot the air-tube,

`by which construction the liquid may tlow freely around the air-tube to the liquid-point, the rapid current of air as it passes ont of 'the air point serving to-exhanst the air within the liquid tube, and ejecting the liquid in spray from the liquid point, the length of ,the horizontal branch being suiiicient to reach into the throat or other place where the difiiculty exists.

lt will be seen from the foregoing that, by unseren'- ing the air-tube or the cap, access is readily obtained to the liquid point, for the purpose ot' removing any obstructionV which may lodge within the liquid tube at its orice of discharge, while my improved atomizcr presents a lighter, mox'e compact and finished appearance, and may be furnished at a less cost than than those as heretofore constructed.

Claims.

NVlmt l claim :is my invention, and desire to secure by Letters Patent, is-

An atomizer, provided with u joint at or near the liquid point or disclmrge-orifice, substantially as and for tbe purpose set forth.

Also, the Combination of an air-tube and a-liquid tube, s o constructed and connected that the air will be forced through the :tiembla in a.. line passing Qeutraily through the liquid point or discharge-Ormea:

substantially as and for the purpose set forth.

Witness my hand this 26th day of July, A. D.

THOMAS J. HOLMES.
